1. A method, comprising:
monitoring a signal to detect transient events at an output of a regulated power converter, wherein the transient events comprise a first transient event and a second transient event after the first transient event;
in response to detecting the second transient event, measuring a transient event period between the first transient event and the second transient event; and
setting a regulation control parameter, of a control engine generating a control signal to control the regulated power converter, to a value determined based upon the measured transient event period between the first transient event and the second transient event, wherein the setting the regulation control parameter comprises at least one of setting a proportional integral derivative (PID) compensator gain parameter of a PID controller of the control engine, setting an adaptive voltage positioning (AVP) droop level of an AVP controller of the control engine, setting an AVP bandwidth of an AVP filtering module of the control engine or setting an inductor current synthesis parameter of a current monitor of the control engine.
